Yes.

USE="test" is a workaround; portage cannot use FEATUREs in dep
strings.  So for example, if the test phase needs a separate tarball of
data (a common enough occurrence) and the ebuild maintainer wants to
download that tarball only if the tests are being run (perhaps the
test data is huge), this can only be done with USE flags.

Basically, if you set FEATURES="test", add "test" also to your USE
flags.  USE="test" should never be used for anything other than
supporting FEATURES="test".
